A mattress can look great in a product photo, then feel completely wrong after one uncomfortable night. That is why mattress types explained properly matters when you are upgrading your bedroom. The best choice is not simply the most expensive option. It is the mattress that suits your sleep position, body weight, bed frame, comfort preference and budget.
From supportive pocket sprung designs to pressure-relieving memory foam and practical hybrids, each style has a different feel. Knowing what sits beneath the cover helps you shop with confidence and bring better comfort to your everyday routine.
Mattress types explained: the main choices
Most mattresses fall into four popular categories: open coil, pocket sprung, memory foam and hybrid. You may also see orthopaedic mattresses, which describe a support-focused design rather than one single construction. Each can be a good fit, depending on what you need from your bed.
Open coil mattresses
An open coil mattress, sometimes called a traditional sprung mattress, uses a connected spring system. The springs move together, creating a firmer and more buoyant feel than foam. These mattresses are often a brilliant value choice for a first home, guest room, children's room or rental property.
Because the spring unit is straightforward, open coil mattresses tend to be lighter to move and kinder to a tighter budget. They also allow air to circulate well, which can help if you prefer a fresher, cooler sleeping surface.
The trade-off is motion transfer. If one person turns over, their movement may be felt on the other side of the bed. They can also offer less tailored support than pocket sprung or hybrid designs. For occasional use or cost-conscious comfort, however, they remain a practical option.
Pocket sprung mattresses
Pocket sprung mattresses contain individual springs housed in their own fabric pockets. Rather than moving as one unit, each spring responds separately to your body. This gives more targeted support around your shoulders, hips and lower back.
They are a popular choice for couples because they reduce the feeling of a partner getting in and out of bed. A pocket sprung mattress can also suit combination sleepers who change position through the night, as it provides a responsive surface without the deep sink-in sensation of some foam beds.
Spring count is worth considering, but it is not the only measure of quality. The depth of the mattress, comfort fillings, edge support and overall build all affect how it feels. Choose a firmness that works for you rather than relying on a high spring count alone.
Memory foam mattresses
Memory foam softens with warmth and pressure, gently moulding around your shape. This close contouring can ease pressure points, making it especially appealing for side sleepers whose shoulders and hips need cushioning. It can also reduce motion transfer very effectively, so you are less likely to notice a restless partner.
The feel is distinctive. Some people love the cradled, settled sensation, while others find it too enveloping or warmer than a sprung mattress. Modern foam mattresses may include breathable layers or cooling fabrics, but a naturally warm sleeper may still prefer a spring-led construction.
Memory foam works best on a supportive, well-ventilated base. If your bed has solid slats, check that the gaps are not too wide and that the frame can properly support the mattress. This helps preserve comfort and prevents uneven wear.
Hybrid mattresses
Hybrid mattresses bring together pocket springs and foam comfort layers. They are designed for shoppers who want the responsive support and airflow of springs with the cushioning benefits of memory foam or other comfort foams.
For many homes, a hybrid is the easy middle ground. It can give side sleepers welcome pressure relief without sacrificing the support that back sleepers often prefer. Couples with different comfort preferences may also find a medium hybrid a sensible compromise.
As with any mattress, look beyond the word ‘hybrid’. Thickness, the number and type of foam layers, spring unit and firmness rating can vary greatly. A deep hybrid may feel more luxurious, but make sure your fitted sheets have enough depth to fit it properly.
What does orthopaedic mattress mean?
An orthopaedic mattress is made with firmer, support-led comfort in mind. It is often chosen by people who want extra stability across the back and hips, particularly back or front sleepers. However, there is no single universal standard for the term, so it should not be treated as a medical claim.
A firm orthopaedic mattress can feel excellent if you prefer a flatter, more supported surface. Yet firmer is not automatically better for everyone. Side sleepers may find a very firm mattress puts too much pressure on their shoulders and hips. If you wake with numb arms or aching pressure points, a medium or medium-firm pocket sprung or hybrid mattress may offer a better balance.
If you have persistent pain or a medical condition, seek advice from an appropriate healthcare professional rather than relying on a mattress label alone.
Choose firmness for the way you sleep
Firmness is personal, but your usual sleeping position is a helpful place to start. Side sleepers commonly feel most comfortable on a medium or medium-soft mattress that cushions the shoulders and hips. Back sleepers often benefit from medium-firm support to help keep the spine in a more natural position. Front sleepers usually need a firmer, flatter surface so the hips do not dip too deeply.
Body weight can change the experience too. A mattress will generally feel softer to a heavier person and firmer to a lighter person. This is one reason online ratings should guide your choice, not make it for you.
For a shared bed, think about both sleepers. A medium-firm pocket sprung or hybrid mattress is often the most versatile option, particularly where one person is a side sleeper and the other sleeps on their back. Good edge support is also valuable in a double, king size or super king, as it gives you more usable sleeping space.
Match your mattress to your bed and room
Before choosing, measure your existing bed frame and check the mattress size carefully. Standard UK sizes include single, small double, double, king size and super king, but dimensions can vary slightly between products. A small double is useful where space is limited, while a king size gives couples extra room without taking over the bedroom.
Your base matters as much as the mattress. Divan bases provide an even platform and often add useful drawer storage. Slatted bed frames offer a lighter, contemporary look, but the slats should be securely fitted and suitably spaced. Ottoman beds are ideal when you need to make every inch of a smaller bedroom work harder, giving you hidden storage beneath the mattress.
Also consider access. A thick, heavy mattress may be more difficult to take upstairs in a narrow terrace or through a compact flat hallway. Measure doorways, stair turns and the bedroom before delivery day, especially when upgrading to a larger size.
A practical checklist before you buy
Do not choose by appearance alone. Think about whether you sleep hot, share the bed, need extra support, have limited bedroom space and prefer a bouncy or contouring feel. Then check mattress depth, firmness, size and the type of base you own.
It is also worth protecting your investment from the first night. Use a breathable mattress protector, rotate it as directed by the manufacturer and allow it to air regularly. Unless the care label specifically says otherwise, most modern mattresses should not be flipped because their comfort layers are designed to sit on top.
At Furniture World, choosing the right mattress is about bringing together comfort, style and value for the way your household really lives. Whether you are furnishing a first flat, refreshing a family bedroom or completing a new ottoman bed, start with the feel you want every morning. The right mattress should make bedtime easier to look forward to and waking up a little easier too.
